Description
What Happened?
Starting with v1.31.0, docker-env will fail if the ~/.ssh directory doesn't exist. This is the case on most linux hosts that have not generated ssh keys (e.g., short-lived VMs).
Introduced in #15452.
The workaround is to run mkdir -p ~/.ssh.
➜ minikube start

✨ Automatically selected the docker driver. Other choices: none, ssh
📌 Using Docker driver with root privileges
👍 Starting control plane node minikube in cluster minikube
